TROLLEY-POLE GUIDE.

Specification of Letters Patent.

Patented July 13, 1909.

Application filed December 26, 1908. Serial No. 469,269.

To all whom it may concern:

Be it known that I, James P. BRENNAN, a citizen of the United States,residing at Centralia, in the county of Columbia and State ofPennsylvania, have invented certain new and useful Improvements inTrolley- Pole Guides, of which the following is a specification.

My invention relates to an improved trolley pole guide, the object ofthe invention being to provide a trolley pole with an improved guide,fulcrumed between its ends on the trolley wheel ournal-pin, and to oneend of which the trolley rope is to be secured, the opposite end of theguide providing a wide trolley wire engaging surface to direct thetrolley wheel into engagement with the wire.

A further object is to provide improved means for limiting the pivotalmovement of the guide, and provide an improved guide of simple,inexpensive construction, strong and durable in use.

With these and other objects in view, the invention consists in certainnovel features of construction, and combinations, and arrangement ofparts as will be more fully hereinafter described and pointed out in theclaims.

In the accompanying drawings, Figure 1, is a view in elevationillustrating my improvements. Fig. 2, is a view in elevation at rightangles to Fig. 1, and l 3, is a detail View of the journal pin.

1 represents a trolley pole having a forked end 2, in which a trolleywheel 3 is mounted to rotate upon a journal pin 4, the latter projectingthrough alined openings in said forked head My improved guide comprisestwo members 5-5. These members are bent from strips of sheet metal andare secured together at their lower ends as shown at 6, and are thenflared outward from each other as shown at 7, and then extend parallelon oppo site sides of the head 2 and are given a general compoundcurvature as shown at 8. The members 55 then project inwardly towardeach other and in close proximity to the periphery of the trolley wheel3 as shown at 9, and are then bowed outwardly from each other and givena general compound curvature, as shown at 10, constituting a widetrolley wire engaging surface, which will direct the wire from eitherside to the center of the guide, to the trolley wheel 3. The edges ofthe parallel members of the forked head 2, are slit and bent outwardforming steps 11, which latter lie in the path of the inwardly bentportions 9 of the guide, so as to limit the pivotal movement of theguide on the pin 4.

The lower end of the guide where the two members 5-5 are securedtogether, is pro vided with an opening 12 to receive the ordinarytrolley rope, so as to manipulate the trolley pole to guide the trolleyin position, or draw the pole down as the case may be.

The pin 4. is made with a head 13 at one end and a locking pin receivingopening at its other end, and the headed. end of the pin 4 is made witha key 14 to enter a key-way in one guide member 5, so as to compel thepin to turn with the guide and prevent rotary movement of the pin whenthe trolley wheel turns.

in operation, assuming that it is desired to direct the trolley wheelagainst the trolley wire, the operator, by grasping the trolley ropesecured to the lower end of the guide members 5, can swing the poleuntil the trolley wire engages any portion of the wide surface 10 of theguide when by releasing the pull on the rope, the cam action on theguide against the trolley wire will move the pole to a position with thewire on the trolley wheel. When a downward pull is made on the guide,the latter being fulcrumed at the pin l, the members of the guide willengage the shoulders 11 to properly position the guide to best engagethe trolley wire, and when a pull on the guide is released, the latterwill assume a position out of contact with the cross wires supportingthe trolley wire, such as is ordi narily in use.

Slight changes might be made in the general form and arrangement ofparts described, without departing from my invention, and hence I do notrestrict myself to the precise details set forth, but consider myself atliberty to make such changes and alterations as fairly fall within thespirit and scope of my invention.

Having thus described my invention what I claim as new and desire tosecure by Letters Patent is:

1. The combination with a trolley pole, a forked head, of a journal pinlocated in said head, a trolley wheel mounted on said pin in the forkedhead, a trolleyguide straddlingthe head and fulcrumed between its endson said pin, the lower end of said guide adapted for the attachment of atrolley rope, and the upper ends of said guide bent inwardly toward theperiphery of the trolley wheel, and then flared outwardly formingguides, and shoulders struck u from the body of the head and againstwhich the inwardly bent portions of said guide are adapted to engage andlimit the pivotal movement of the guide.

2. The combination with a trolley pole and a forked head, a journal pinlocated in said head, a trolley wheel mounted on said pin, a trolleyguide, comprising two metal strips located at opposite sides of the headand fulcrumed between their ends on said pin, the lower ends of saidstrips secured together and provided with a rope receiving opening, theupper ends of said stri s bent inwardly toward the periphery of iihetrolley wheel and then flared outwardly forming guides, shoulders struckup from the body of the head and against which the inwardly bentportions of the said strips are adapted to engage and limit the pivotalmovement of the guide, and said pin having a head at one end, securingmeans at its other end, and a key at the headed end located in a key-wayin one of said strips.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
